I think the traditional explanation is that demons just find someone, they pick on them and try to break down their spirit so they can... take control of their bodies. Why exactly? I don't know.

Really it's always things that scare me like loss of control, dealing with the unknown and the unseen... Something that's not supposed to be there and you don't know where it came from, or what it wants from you, or how to defend yourself against it. That's the root of the things I find scary.

I'm just considering myself extremely lucky. All I wanted is to have 'Paranormal Activity' be released and become successful. And everything that's happened since then is just an enormous bonus.

By trade, I am a software programmer, so I never really had any experience with movies before. I started out with 'Paranormal Activity.

In many places around the world, all over the U.S. and Europe there are active nuclear power plants. And for many years during the Cold War the threat of nuclear war was a permanent fear. There's always the concern that human kind is biting off more than they can chew in harnessing nuclear power.

I don't know if I would say that I'm specifically a history buff. I do find a lot of things fascinating, especially anything that's bizarre or mysterious and unknown and we don't have all the answers for.

I do not buy CDs any more; I usually stream Internet radio. For movies, I hardly every buy any DVDS. I have a DVR, so just record things off HBO, Showtime and so on.
